very useful little kit
The brackets work much better than some of the cobbled together mounts I've seen. Keeping the sensor in a fixed position is key to repeatable performance.

+/- an inch from a couple inches to across the room. Good enough
Eh, for less than 2.50/sensor it's pretty reasonable accuracy, and pretty easy code for Arduino. If you want mm accuracy this will not cut it. But +/- an inch over several feet is good for the price.

Works as expected
Works as expected with the Arduino platform.

Working well
I bought two packages of these 5pc sensors for my son's science project team. All of them work well. Very fair price. The pin layouts are good and the circuits are well soldered. -1 points because it doesn't come with mounting adapter for each of the sensors.

Very well made and very well worth the money
I needed these to sense the level of my rain water tanks and they worked well enough to give me an accurate enough water level.

Fits just fine
Mainly bought it for the ultrasonic sensor holders which fit amazingly

Good for hobby and experimentation
These are very economical for hobby and experimentation. There is a slight difference between the five units in the close range readings and sensitivity when the devices are used for measuring distance. Otherwise good value for non-critical applications.

Simple replacement and repair for the part in my OpenGarage unit
I bought an OpenGarage unit a few months ago, and that project uses an HC-SR04 like these. The one in the OpenGarage project simply stopped working - and many comments online say that HC-SR05 modules are semi-reliable at best. The replacement was super-simple - and I have 4 more if and when this might fail. Now everything is working as well as new! Very Happy Me

Arrivati esattamente come da foto! i supporti sono in plastica (non in cartone :D) bisogna avere un po di delicatezza per inserire correttamente il circuito sul supporto. Confezionati singolarmente in bustine richiudibili, a sua volte contentenute in un robusto box in cartone. il tutto chiuso dento il classico cartone C1 di Amazon. 10 stelle per la cura del confezionamento, nessun piedino storto! A breve ne uso un paio e vi faccio sapere!

War einfach an einem Raspberry in Betrieb zu nehmen. Anleitungen dafür sind im Internet leicht zu finden. Versieht jetzt seinen Dienst als Füllstandsmesser am Öltank. Die gemessenen Entfernungen sind OK.

Los he usado con un ESP8266 (WEMOS D1) y funcionan correctamente, para conectarlos hay muchos esquemas de como hacerlo en google.
